Is there any way to get rid of this annoying bug.
MacBook Pro (13-inch Mid 2012), OS X Mountain Lion (10.8.4)
Can't confirm.
Are you doing something with full screen mode?
I have the exact same issue in mountain lion that you describe. i sometimes have luck by closing my macbook pro, waiting for the external display to flash (power cord plugged in) and then disconnecting the external display cable, and then re-opening my macbook pro. i've also solved it by typing "killall Dock" at a terminal window. but still, it's a bug!
Nice to know i'm not the only one experiencing this bug. This also means that if more people are experiencing this error then it's more likely to get the attention from apple, which in the end could lead them and there crew to fix this annoying error.
Awesome! Thanks, this issue has been driving me crazy for ages! killall is way better than closing everything and restarting 🙂
You're welcome! I've since upgraded to Mavericks, and found that the problem doesn't exist anymore, though now there's a whole new, slightly less annoying problem -- when my laptop goes to sleep while attached to an external monitor, when it wakes up, the windows are in strange and unusual locations! So I have to go and rearrange them all like they were ... sigh ...
Yeah Weird, I'm on Mavericks and it still happens to me 😟 . Oh well I'm not so fussed now that I have a workaround!
Mission Control overview error occur when plugging out external screen monitor (using dvi hdmi cable). Mission Control windows then remain invisible until you eventually restart your computer. Annoying error. Need fix/patch. Running Mountain Lion.
